SPECIFICATION forming part of Letters Patent N o. 746,857,6.atedDecember 1 5, 1903.

Application led February 11, 1903. Serial No. 142,967. (No model.)

To al?, whom t may concern,.-

Be it known that I, MICHAEL R. MANGAN, a' citizen of the United Statesof America, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in WireMattresses,

of which the following is a description.

My invention belongs to that class of Inattresses in which the wire isformed into a web which is resiliently supported in the main frame ofthe mattress.

The object of my invention is to produce a simple, effective, andeconomical device of the kind described; and to this end it consists inthe novel construction, arrangement, and combination of parts hereinshown and described, and more particularly pointed out in the claims.

In' the drawings wherein like reference characters indicate like orcorresponding parts, Figure lis a. plan view of my invention. Fig. 2 isa plan view of one of the parts going to make up my mattress. Fig. 3 isan edge view of the same. view of a section of a mattress, showing themethod of constructing the same. Fig 5 is a plan view of one of theoutside members going to make up the mattress-web, and Fig. 6 is an edgeView of the same.

In the drawings, l l represent the side bars, and 2 2 the end bars,goingto make up a mat- 'cross-frame.

3 3are coiled springs or equivalent members secured to the end bars 2 2,to which the web of the mattress is secured, giving resiliency thereto.The web of the mattress is made up of a plurality of V-shaped members 4,consisting of two arms extending at an angle from each other andconnected by a loop or eye 5. The free ends of the two arms terminate indownwardly-projected hooks 6, for a purpose hereinafter described. Theside members of the web are composed of members 7, each provided with along arm S, which when connected'with a similar member will extend in astraight line to form the outer edge or border of the mattress, and ashorter arm 9, extending at an angle from the main arm 8. The two armsare joined by an eye or loop 10, as are the main members4 of the web, byeyes 5. The free ends of the arms 8 and 9 Fig. 4 is an enlarged detailare also provided with downwardly-projected hooks 1112, for a purpose tohe described.

The method of assembling the parts may be briefiy described as follows:Commencing liat the top of Fig. 1 the eyes or loops 5 and .10 are eachsuitably engaged With'one of the springs 3, the arms of the membersextending therefrom. The next row of members is then placed in positionby engaging the hooks l2 of the arms 9 in the eyes 5 of'one of the members^4 and also the hook 6 of the adjacent member 4 within the same eye,so arranging the series across the mattress to form the on the proximatearms 4 are engaged with'an eye or equivalent member formed on thesprings 3 at that end of the mattress, completing the web and bindingthe whole firmly together.l When thus formed, the whole constitutes asimple, eective, and very economically-constructed wire mattress adaptedfor all the usual purposes for which such articles are generallyemployed.

It will be noted that when assembled the extending arms of the parts 4extend in the same general direction-that is to say, tley form asubstantially straight line extending diagonally across the mattress andadding greatly to the strength thereof. It will also be noticed that theshort arms 9 of the part 7, arranged on the sides of the mattress, arethe initial members from the side to form the diagonal lines referredto. This adds great strength to the device, prevents sagging from use,and greatly increases its durability.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a device of the kind described, a mattress-frame comprising sideand end barssuit1 ably connected, in combination with a web composed ofV-shaped members 4 each pro- IOO vided with eyes 5, and side members 7provided with an eye 10, Vthe extending arms of the two adjacentV-shaped members being connected to one of said eyes 5, the wholeconstituting a complete web, and means for resiliently connecti-ng theweb to the ends of the frame, substantially as described.

2. In a Wire mattress, the side and end bars suitably connected, incombination with a web composed of V-shaped members 4 provided with eyes5, and side members 7 pro-Nv vided with eyes 10, the adjacent arms ofthe side members being engaged With one of the eyes 5, as set forth, theangle of the arms of the V-shaped members being such that when the webis completed the arms will extend diagonally across the mattress insubstantially a straight line, substantially as described.

3. In a device of the kind described, the side member-7 provided with anarm 8 andashorter arm 9 connected by an eye 10, the free ends arms 6With one of the eyes 5 in making up the mattress said arms will extenddiagonally across the mattress in substantially a straight line,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

MICHAEL R. MANGAN.
